Windows 2000 Professional Update problem

I have been trying to download the latest updates for Windows 2000 Prof but I
keep getting a missing file message that reads: missing "DATA1STD.MSI' please
select path to download file. I'm totally lost. I don't have the disks that
it asks for and I have tried to find the file at MSN, but no luck. Can
anybody help me out? What is this file and where can I get it?

PS. I recently deleted all my internet history, cookies etc. to make space.
Could this have anything to do with it?

Desparately in need of help. Thanks.
